GAS: A novel grid based authentication system

Abstract

With the evolving trends in technology, providing security for the users is an essential goal of the application. Authentication is one such important aspect of security which provides access control for the users of an application. The common method to provide authentication is by using a username/password pair. Graphical password authentication has proved to be more powerful and useful when compared to traditional textual password authentication. In this paper we propose a novel graphical password based authentication system called GAS(Grid based Authentication System). We focus our attention on the epigram, “It is easy to remember what we see rather than what we hear”. The methodology involves choosing a pattern called Auth Pattern which is formed by placing images in a given grid. We have chosen an optimal size for the grid as 8*8.Our proposed system considers very important parameters such as user memory and length of the password. Considering these parameters we compare our system with the state of the art authentication systems to prove our methodology’s efficiency.
